Outline of Power Supply
The MJ unit is not equipped with a protective device for the motor. Thus, power must be supplied
from the machine tool circuit equipped with a protective device.
To operate the MJ unit separately, provide an electrical component equipped with a protective
device (push-button switch with overload protection device, fuse-less breaker, or earth leakage
breaker).
To operate the MJ unit separately, an optional electrical component equipped with a protective device
(push-button switch with overload protection device, fuse-less breaker, or earth leakage breaker) is
available.

When installing a fuse-less breaker or an earth
leakage breaker, make sure to install it together with
a push-button switch equipped with an overload
protection device (see the diagram on the right).

Wire power to the terminal box.
Note: Do not connect only a fuse-less
breaker or earth leakage breaker. A
push-button switch with an overload
protection device must be installed
as a set.
